A: The PLC turns ON INHIBIT and sends the execution command to the DeviceNet Remote ID
Controller.
B: The DeviceNet Remote ID Controller checks that INHIBIT
is ON, determines the CMD (command),
LEN (data length), and ADDR (start address), and then turns ON BUSY.
C: The DeviceNet Remote ID Controller starts communications with an ID Tag when one enters the
Antenna's communications range.
D: The DeviceNet Remote ID Controller turns ON NORM when communications with ID Tag end
normally.
E: The ID Tag moves outside the Antenna's communications range within 100 ms after the DeviceNet
Remote result is output.
F: The result output is turned OFF 100 ms after the DeviceNet Remote ID Controller result is output.
G: The DeviceNet Remote ID Controller starts communications with ID Tag when it enters the Antenna's
communications range.
H: The DeviceNet Remote ID Controller turns ON NORM when communications with the ID Tag ends
normally.
I: Result output is turned OFF when the ID Tag moves outside the Antenna's communications range
100 ms after the DeviceNet Remote ID Controller result is output.
J: The PLC turns OFF INHIBIT
to prevent command execution by the DeviceNet Remote ID Controller.
K: The DeviceNet Remote ID Controller confirms that INHIBIT
is OFF, and then turns OFF BUSY.
